摘　　要：为了探讨蚜虫对不同色光选择反应的定量指标,采用滤光片技术测定了有翅和无翅桃蚜Myzus persicae对不同波长单色光的趋性反应。结果表明:有翅蚜对490～550nm范围内的单色光表现出明显趋性,其中对538.9和549.9nm的绿偏黄色光趋性最强,平均位移分别达25.29和22.97cm,其次为491.5nm的蓝绿色光,而对于波长576.0nm的黄色光并没有表现出明显趋性。无翅蚜对不同单色光的趋性反应则没有明显的峰值,最高相对平均位移仅1.41。行为测定结果与前人电生理测定的结果基本一致,说明以位移作为小体昆虫趋光性强弱的指标是可靠的。In order to explore the quantitative index of aphid selection responses to different lights,bioassays on the phototactic response of alate and apterous Myzus persicae to different monochromatic lights were conducted using filter technology. The results showed that the alate aphids were significantly attracted by the monochromatic lights with the wavelength ranging from 490 to 550 nm. Among the spectra,the yellowish green light of the wavelength 538.9 and 549.9 nm elicited the strongest behavioral response o...
